PRECAUTIONS
General Precautions (Cont'd)
• After disconnecting vacuumorair hoses, attachatag to
indicate theproper connection.
• Use only thefluids andlubricants specifiedinthis manual.
• Use approved bondingagent,sealants ortheir equivalents
when required.
• Use tools andrecommended specialtoolswhere specified
for safe andefficient servicerepairs.
• When repairing thefuel, oil,water, vacuum orexhaust
systems, checkallaffected linesforleaks.
• Dispose ofdrained oilorthe solvent usedforcleaning parts
in an appropriate manner.
Precautions forMultiport FuelInjection System
or ECCS Engine
• Before connecting ordisconnecting anyharness connector
for the multiport fuelinjection systemorEGM (EGGS control
module):
Turn ignition switchto"OFF" position.
Disconnect negativebatteryterminal.
Otherwise, theremaybedamage toEGM.
• Before disconnecting pressurizedfuellinefrom fuelpump to
injectors, besure torelease fuelpressure.
• Becareful nottojar components suchasEGM andmass air
flow sensor.
Precautions forThree WayCatalyst
If a large amount ofunburned fuelflows intothecatalyst, the
catalyst temperature willbeexcessively high.Toprevent this,
follow theinstructions below:
• Use unleaded gasolineonly.Leaded gasoline willseriously
damage thethree waycatalyst.
• When checking forignition sparkormeasuring engine
compression, maketestsquickly andonly when necessary.
• Donot run engine whenthefuel tank level islow, otherwise
the engine maymisfire causing damage tothe catalyst.
Do not place thevehicle onflammable material.Keepflamma-
ble material offthe exhaust pipeandthethree waycatalyst.
Engine Oils
Prolonged andrepeated contactwithused engine oilmay
cause skincancer. Trytoavoid direct skincontact withused oil.
If skin contact is.made, washthoroughly withsoap orhand
cleaner assoon aspossible.
HEALTH PROTECTION PRECAUTIONS
• Avoid prolonged andrepeated contactwithoils, particularly
used engine oils.
• Wear protective clothing,including impervious gloves
where practicable.
• Donot putoily rags inpockets.
• Avoid contaminating clothes,particularly underpants, with
oil.
• Heavily soiledclothing andoil-impregnated footwearshould
not beworn. Overalls mustbecleaned regularly.
• First Aidtreatment shouldbeobtained immediately foropen
cuts andwounds.
• Use barrier creams, applying thembefore eachwork
period, tohelp theremoval ofoil from theskin.
